Based on Figure 3, create a class named Child that inherits the Father class. Declare an instance name location (String) for class Child. 2. Define a constructor in class Child and give an appropriate initial values for the instance (name, age, location). 3. Define a method display () in class Child, execute the display ( ) method in superclass using the keyword super. Method display ( ) in class Child should print the information of name, age and location 4. Create other class named Main for the main method and create 2 objects for the 2 classes (Father and Child). Then execute the display ( ) method for Father and Child. Example of the output as in Figure 4: Father's info: Name: Josh Age: 50 Child's info: Name: Christy Age: 20 Location:…
- Consider the following classes. public class Base { public Base() { System.out.print("Base" + " "); } } public class Derived extends Base { public Derived() { System.out.print("Derived" + " "); } } Assume that the following statement appears in another class. Derived d1 = new Derived(); What is printed as a result of executing the statement? A) Nothing is printed because the statement is a variable declaration. B) Base C) Derived D) Base Derived E) Derived BaseDefine the class bankAccount to store a bank customer’s account number and balance. Suppose that account number is of type int, and balance is of type double. Your class should, at least, provide the following operations: set the account number, retrieve the account number, retrieve the balance, deposit and withdraw money, and print account information. Add appropriate constructors. Derive the class checkingAccount from the class bankAccount. This class inherits members to store the account number and the balance from the base class. Add member variables to store minimum balance and service charges amount if the balance falls below the minimum balance as additional information. In addition to the operations inherited from the base class, this class should provide the following member functions to performs: set interest rate, retrieve interest rate, set minimum balance, retrieve minimum balance and set service charges, verify if the balance is less than the minimum balance, write a…Define the classbankAccountto store a bank customer’s account number and balance.

Add appropriate constructors. b.Every bank offers a checking account. Derive the class checkingAccountfrom the classbankAccount(designed in parta). This classinherits members to store the account number and the balance from the base class. A customer with a checking account typically receives interest, maintains a minimum balance, and pays service charges if the balance falls below the minimum balance.

The above code compiles but causes runtime error. b. The above code has no issues. It compiles and runs. c. The above code causes compiler error.Java Programming Create "Mammal" class as a parent class and "cat" as a child class Mammal(Superclass) Attributes name Methods move() eat() cat (Subclass) Attributes age Methods dispaly() eat() Override eat method in cat subclass. Print something in methods such as in move method you can print “I can move”. Test the inheritance with creating objects and calling parent and child methods. Create object of a child class by passing arguments to the constructor.
